Depth setting rings

Where can I buy those press-fit rings that you often see on small cutters? I have seen them on small drills and mills used for engraving.

I found 1/8" ones at Drill Bit City for really cheap ($11 for 100!)

How about 1/4" ones?

I have been making my own out of 1/4" thick UHMW. They actually work pretty well but need a drop of CA to lock hard. Send me a pm if you can't find any, I made a number but they will need to have some tape adhesive cleaned off.
